chlorinatedphenols and other solvents and incorporated stiffeningmaterial which may include Montan wax.

A number of amido-phenols are desirable" finish solvent or softeningagents suitable for use in finish removers. Xylidin is quitesatisfactory and the anisidins, such as ortho, meta and para-anisidinare also desirable sol- :vents. Ortho-anisidin in its pure form has aboiling point of about two'hundred and eighteen degrees C. and theordinary commercial form is a solvent liquid having very little odor andpossessing a somewhat basic or antacid character because of the presenceof the amido group. Many chlorinated phenols are also desirable finishsolvents which may, with advantage be incorporated in finish removers.Among these solvents, the ortho, meta and para monochlorcresols may beused as well as chlorguaiacol, chlorcreosote and chlorinated woodcreosote. These solvents may of course be incorporated with other finishand loosening agents, such as penetrating solvent material, that is,finish solvent or softening material of a generally benzolic characteror action in removers such as benzol and its homologues, t'oluol, xyloland their commercial forms such as commercial toluol and the highboiling point coal tar solvent naphtha and also the somewhat analogouspetroleum hydrocarbons such as benzin, light kerosene, the high boilingpoint petroleum product naphthenic acid having a boiling point of twohundred and fifty to three hundred degrees C. and a specific gravity ofabout 1.9 which may be separated from the alkali compounds formed inpetroleum refining. @ther suitable penetrating finish solvents are woodturpentine, turpentine, and Russian turpentine, which is a still bettersolvent for most finishes than ordinary turpentine and having adesirable odor, as well as tar oil, oil of camphor and the light orethereal oils of camphor, and also chlorinated solvents suchSpecification of Letters Patent.

as carbon tetrachlorid, dichlorhydrin, epichlorhydrln, chlorbenzol,bensylchlorid and benzalchlorld, which is a'very eifective finishsolvent and which together with benzylchlorid occur inchlorinatedtoluol, a noninflamniable body having desirable infiam-'mab1l1ty suppressing action in removers.

Suitable loosening finish solvent material may also be usedwithadvantage in most solvents of a-generally alcoas methyl ethyl propylbutyl am 1 all 1. benzyl and otheistrict alcohols p'r dferab ly in theircommercial forms including denatured' alcohol or their esters whencombined with acetic, carbolic or other acids and many ketonic looseningsolvents may be used, such as methyl ethyl ketone, ethyl butyl ketone,methyl acetone, and their condensation derivatives and the secondary andtertiary alcohols and their derivatives.

For ordinary service it is desirable to incorporate suitable stifl'eningmaterial with the composite solvents ordinarily employed so as topreferably have an effective film formlng action and correspondinglysuppress the evaporation of the solvents. Parafl'in, ceresin, ozocerite.beeswax, Japan Wax and other generally waxy thickening material may beused, Montan wax being an especially desirable hard wax having anefi'ective thickening action under conditions. The crude Montan Wax is abrownish material similar to ozocerite and contalning montanic acidwhile the refined wax is white and somewhat crystalline Other stiffeningmaterial such as wood flour, starch, infusorial earth, pyroxylin, othercellulose esters, scrap celluloid, and fatty, soapy or alkaline. bodiesmay also be used. The use of such antacid soapy material havmg analkaline reaction or of anilin or other antacid agents such as theamido-phenols referred to, are of course desirable with some chlorinatedsolvents which have an appreciable acid tendency. A desirableillustrative remover of this character, which is practicallynon-inflammable, may comprise ortho-anisidin ten parts, naphthenic acidhot weather twenty parts.

Another suitable illustrative remover may comprise ortho-anisidin tenparts, caustic soda two parts. chlorinated toluol twenty parts, paraffinwax two parts, bayberry tallow one part, celluloid scrap five parts andmethyl acetate forty parts.

Another illustrative remover may be formed from ortho-anisidin twentyparts, naphthcnic acid twenty parts, monochlorcresol twenty parts andceresin wax five,

parts.

Another lllustratlve remover may comprise methyl acetate one hundredparts,

- caustic soda two parts, ortho-anisidin twenty parts, carbontetrachlorid twenty parts, parafiin wax two parts.

Another desirable composition is one hundred parts ortho-a-nisidin,sixty parts ethyl alcohol, forty parts carbon tetraehlorid and tenpartsparaflin wax.

Another suitable remover may comprise ninety parts ortho-anisidin, fiftyparts naphthenic acid, fifty parts acetone, and twelve parts paraifinwax.

1. The non-inflammable finish remover comprising approximatelyortho-anisidin ten parts, naphthenic acid fifteen parts, benzal chloridtwenty-five parts, anilin five parts, monochlorcresol ten parts, benzylalcohol forty parts, ethyl alcohol ten parts and incorporated stiffeningmaterial including Montan wax four parts, paraflin wax three parts andlaundry soap three parts.
